ABSTRACT:
The present invention provides apparatus attachable to an Alpine ski boot for aiding the wearer in walking. This apparatus comprises an auxiliary sole attachable under the sole of the ski boot and having an upper surface for accommodating the ski boot sole and a lower surface for engaging the ground. A given curvature is provided on the lower surface for approximating the normal heel-to-toe walking motion. A pocket in a leading end portion of the auxiliary sole surroundingly engages a toe portion of the ski boot sole. An elongate, elastically deformable cord grippingly engages the heel portion of the ski boot. This cord has a pair of studs attached to its respective ends. A plurality of stud-engaging slots are spaced at predetermined intervals longitudinally of the auxiliary sole for releasably engaging these studs to provide a range of adjustment of the effective length of the unstressed cord.
